To all A2li/imi@ may oomezm:

lie it known that I, CHARLES S. FAKK, a citizen of the United States, residing at Savannah, in the county of Chatham and Siete of Georgia, and usefu iiipiovements in Uiosiiie Devices foi' Tonks, ze., of which the foiiowinis e. speeiiicot-ion.

Referring to he drawing annexed by eefeience diameters, o designates the neck oi' :nipple of the izmir oi' other reeeptacie, this neck being provided meer its upper end, on its interior gurfiiee, with en ennuie? im werdipeemjiiog Hooge .7), whieh is coilinuoiis except at one point in the cieeiim ference of the meek). at which point the iaiige is omiieil io ioim a theo-1 o, the two ends of the Hen-ge et this point being he"- eied ilespeetiveiy upwediy :mei ownwnry ai (i.

The eovei e is povided .at its underside with o. eii'eeia'r projection ,r2 which fits looseiy wihin the neck o and' is adapted to engage the Hooge when the cover is moved to a closed posiioii. Riveted or oheiwise affixed to the underside of the cover is e metal disk y of suiieieiit diametei' to erim tend nearly to the edge of he projecting part f of the cover. The edge of the disk is bent away from the body-poi'ion hereof and the bottom of the cover to form en an nuiaioetwardijwprojeeting clamp-Harige iz. This hmgze ii, ike the neck {iange Y), is Continuous except -zit one point in its iength, where it together with saifi body-portion is spiit radially io form a pair of'resiiient fingers z', one of which curves iipwaidiy :md the othei downwardly, 'forming a throatlike passage j between the ends of the have invented certain new,

ihis invention' relates to' eiosnre devices 'sruced that izhe neeeseiizy fingers. The disk is aise eioteii on the line of connection heie/een the Hnge emi bodyporeion, seid skit-extending on botiieides of the radial .Split and :it right-angles izhez'e to, vso that the z'esiiieh fingers 2'- eie epiiee from said body-poi'tion and are' connected only to he aiige.

-To lock the cover to v(the neck ii', meeessury'o piece it thei'eon, with fizmge k iesting upon the .Hnge ui'ii the cover to the righi, downwardly turned iigei z Wiil engage under the bevei d which exiiende epwezediy, und the continuous rotation of ehe eover Wiii eirrry ehe Einige fi, undef the iaii'ge Z. emi thus drew Athe @over 'eeiiieiitiy but eightiy to its see on he neck. A ii tem is simply its @lamp A, om?, then whereupon the of the cover ie iieoeseei-y rto eompeieiy seat' he' cover, but eoiiiiiuerijiiining in *bhe seme dii'eetion does not diiiw eoieje any@ tighter to its seat rior fioes'iz eend to oiioeif the coveif.' To miioekxiid i'emoif'e the eover, it is simpy necessary to tum it te 'ihe left, whereupon the upweiy sum'e iiigef: wil slide up over he upwardiyfoevee part rl of the iiange o and thus come 'iie ange h to pase up ii'oegh the-oei: o and around on 'top of the Han-ge I) iiiieii ehe iange h throughout its entire length "has passed up through the 'iiiroet c.

ehaiacieiiszie of my device is ie simpiieiiy; it requises of construction and opeietion. no arms or steps oi' theede, :imi is so eoiio stoppii'ig :the rooion 'of :the cover eeitaizi point is eliminated. The elimination of screw" .threads oes away wih ehe annoyance of catching the ini'eads wrong and time emesing or stripping the hieeds. My device posiiiveiynioeis the cover in piace by ieesoii of Vthe fact that `he resilient Harige is workeci enii'eiy undef the rigid flange and thus eliminaies 'the chance of it being shaken off.

R is obvious 'ihm my device may he need for e greet variety of purposes. For example,v it is capable. o effective iise'as o,
